PIPE-VISE CLAMP.

Specification of Letters Patent.

Application filed March 29, 1915, Serial No. 17,663. Renewed March 15,1917. Serial No. 155,092.

To all whom it may concern:

Be it known that I, IVALLAGE F. VVoLFn, a citizen of the United States,residing at Schenectady, county of Schenectady, and State of New York,have invented certain new and useful Improvements in Pipe-Vise Clamps,of which the following is a specification.

The invention relates to such improvements and consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompanying drawings, and tl'le'referencecharacters marked thereon, which form a part of this specification.Similar characters refer to similar parts in the several figurestherein.

Figure 1 of the drawings is a horizontal, cross-section of an uprightcircular post, showing a top plan view of 'my improved pipe-vise-clampapplied to the post.

Fig. 21's a view in side elevation ,of the upright post with the clampapplied thereto,

showing a pipe-vise supported by the clamp.

Fig. 3 is a plan view of the inner side of Fig. 4 is a central,longitudinal section of the same taken on the broken'line 4:4: in Fig.3.

Fig. 5 is a horizontal, cross-section of an oblong rectangular post,showing a plan view, partly in section, of a modified form of clampembodying my invention.

Fig. 6 is a top plan View of the base-plate of the clamp partly brokenaway.

Fig. 7 is a vertical, longitudinal section of the same taken on thebroken line 7-7 in Fig. 8 is a plan view of an extension bar for thebase-plate of the clamp shown in Fig. 5.

Fig. 9 is a plan view of the complementary clamp-member shown in Fig. 5.

The principal object of the invention is to provide a clamping-mechanismwhereby pipe-vises of various kinds can be readily attached to, anddetached from, posts of different sizes and form.

Referring to Figs. 1, 2, 3, 4, 6 and 7. of the drawings, 1 is thebase-plate of the clamp provided with av plurality of slots, 2, adaptedto adjustably receive screw-bolts, 3, whereby the base,4-, of apipe-vise, 5, can be detachahly mounted upon the base-plate, 1, of theclamping-mechanism.

. base-plate, 1, the base of the vise can be so placed upon the outerside of the clampbase-plate,'1, that bolts inserted through theapertures .in the base of the vise can be passed through 'certain of theslots, 2, whereby the pipevis;{ can be detachably mounted upon theouiertide of the clanm-base-plate, as shown in the drawings.

Along the opposite edges of the clampbase-plate, l, on its inner sideare a pair of bearing blocks or flanges, (1, each havinga substantiallyflat face, 7, in which are formed at about the middle of the flange orblock, a series of stepped seats. 8. adapted to receive cylindricalposts of different diameters.

The complementary clamping-member, 9, has on its inner side a flat face,10, in the middle of which are formed stepped seats, 11, similar to thestepped seats, 8.

An eye-bolt, 12. is pivoted at 13 between a pair of cars, 11, on one endof the clampbase-plate. 1, the shank of said bolt being adapted to passthrough an aperture, 15. in the complementary clamping-melnber, 9.

The opposite end of the clanm-base-plate, 1, is provided with anopenslot, 16, and the plate is undercut or recessed on the outer sidealong the edges of said slot to receive the head, 17, of a screw-bolt,18, the shank of which is readily inserted within, and removed from,said open slot.

The shank of the scrmv-bolt, 19, is adapt ed to pass through anaperture, 15), in the complementary clampirig-member, 9; and by means ofnuts, 20, on the projecting ends of the bolts, 18, theclan1ping-1ncmberS can be drawn toward each other to tightly embracebetween thcm a post, as the post, 21, and thus serve to support thepipe-vise in a convenient position for use. 7 w

The post, 21, is shown as a circular or" cylindrical post occupying thestepped seats} clamping-members instead of by the stepped seats, 8 and11.

The clamp can be readily released by loosening one of the nuts, 20,sufiiciently to permit the headed end of the bolt, 18, to be swung outfrom the open. slot, 16.

When the pipe-vise is to be mounted upon a flat-sided post of a widthgreater than the distance between the bolts, 12 and 18, I substitute tor the clamping-member 9, a longer flat clamping-member, 2:2, providedat one end with an aperture, 23, corresponding to the aperture, 15, toreceive the bolt, 12, and at the other end with a series of open slots,.21, into a selected one of which, the bolt, 18, can be laterallyinserted; and I removably mount upon the clamp-base-plate, 1, anextension clamp-bar, :25, provided witha series of bolt-holes, 26, forthe bolt, 18, corresponding in position with the respective open slots,21, in the cla1np-member, 22.

The extension bar, 25, has at one end a tongue, 27, adapted to beinserted between the ears, 14, and between the pivoted end of theeye-bolt, 12, and the inner side of the clamp-base-plate.

Near its other end the extension clampbar, 25, has formed thereupon ahook, 28, adapted to occupy the undercut or recess in theclamp-base-plate adjacent to the open slot, 16.

For convenience in casting the extension bar, 25, the bar may beprovided with an aperture, 29, beneath a part of which the hook, 28,extends.

In applying the extension bar, 25, to the base-elamp-plate, the tongue,27, is slid into its seat between the ears, 1st, at the same time thatthe hook, 528, is slid into the undercut or recess adjacent to the openslot, 16, and when thus seated the pull of the bolt, 18, upon theextension bar, 25, is transmitted to the clamp-base-plate.

The last described construction is shown in Fig. 5 clamped upon anoblong rectangular post, 30.

Instead of using the form of complementary clamping-member, 22, theclampingmember, 9. may be made of suilicient length and provided withadditional bolt-openings, 31, to adapt it for use with the extensionbar,25, as well as with the clamp-base-plate, 1, and in Fig. 4 I have shownthe clampingmember, 9, partly broken away.

What I claim as new and desire to secure by Letters Patent is- 1. Apipe-vise-cla1np, having in combination, a elamp-base-plate providedwith a plurality of bolt apertures for interchangeable connection withthe bases of different pipe-visas and having along its opposite sidesbearing-flanges formed with stepped seats and with extended flatbearing-surfaces on opposite sides of said stepped seats;]

a clamp-member complementary to. said complementary clam mg memberindependently of the base of t e pipe-vise.

2. In a pipe-vise-clamp, and in combination, a clamp-base-plate providedwith boltholes for connection with the base of a pipevise; an extensionbar detachably secured to said clamp-base-plate, both saidclampbase-plate and said extension bar being adapted to receivescrew-mechanism; a clamping-bar complementary to said clampbase-plate;and screw-connections between said complementary clamping-bar; andeither said clamp-base-plate or said extension-bar interchangeably.

3. In a pipe-visc-clamp, and in combination, a clamp-base-plate providedwith boltholes for connection with the base of a pipe vise and with anopening for a clampingbolt', of an extension-bar detachably secured tosaid plate, said bar having a hook cmbracing a portion of the plate atone end and being provided with an opening for a clamping-bolt; aclampirig-member complementary to said clamp-lmse-plate provided withbolt-apertures; a screw-boltconnected with one end of said complementaryclamp- 9 ing-member and adapted to interchangeably occupy theclamping-bolt-openings in the clamp-base-platc and said extensionbar;and a screw-l)olt-conncction between the other end of said complementaryclampingmember and the other end of said clampbase-plate.

In testimony whereof, I have hereunto set my hand this 26th day of March1915.
